SSDiesel glowplugs

[JHoffman93]

Has anyone heard of or used instant-heat gps from SSDiesel Supply? They claim that they don't swell, the pictures look impressive. They also claim that they supply the military with thier gps.

[JHoffman93]

I have been doing some research. It looks like SSDiesel is selling gps made by WAP Inc. out of Indiana. They are a dual coil plug made here in the US. They make gps for tractors, big rigs and many other diesel engines. I wish I could find someone that has used these plugs and what they thought of them.

wap is wellman which is currently what i have in my truck and they seem to be ok

[JHoffman93]

How long have you had them in your truck? Are they the dual element instant heat plug or a single coil? I went to WAP's web sight and they look like a good comp. with good products. Hopefully some others will chim in here. I lost a bid on Ebay for a set of Motorcraft plugs by a dollar. They hadn't been bid on in seven days and in the last 10 min. someone out bid me by a dollar, boy was I mad, I could have had a set of 8 for 50 dollars.

I have heard nothing but bad bout wellmans in the long run. Beru's or a 12 volt plug are the only way to go

David85 had to pull a head to retrieve a Wellman glow plug tip.
I think he has a picture of the piston in his gallery.

450,000 miles, not one problem with Motorcraft/Beru glow plugs.
I think I will stay with the tried and true.

Just remember, if you have to pull a head or replace a piston, Motorcraft glow plugs would be a deal at 50 dollars each.

yeah but for the price of 8 at 50 bucks you could just get a whole new (used) truck

good thing you can get em for 10

My experience with WAP glowplugs was not good.

Ran 080s (the stock drop in replacement) for a while and eventually a manual switch left on too long caused ALL of them to loose their tips in the engine. That was the event that forced my to rebuild my engine. I got these in a mail order from MWFI thinking they would send me beru plugs.

I tested an 088 (this is supposed to be a dual coil) and it started swelling right around the 9 second mark. After 23 seconds it let out a little puff sound and the tip finally ruptured and power stopped flowing. By then it was about 5/16" thick which could not have been removed from an engine.

I did read a lot of good things about WAP plugs including that they were made in USA (generally a good thing!), used for military contracts, used in humvees that have to be idiot proof, and so on. In the end they did not live up to the reputation. Maybe I had a bad experience or maybe it was a bad batch during that era but let me tell you there needs to be a large loaded gun pointed to my head to ever install a set of wellman plugs again.

My advice to anyone that is thinking of trying a new brand or type of glow plugs is to test them to really see if they are self regulating as they claim.

I did manage to burn out a set of beru plugs in similar fashion as the 080s (thanks to a deffective controller) and they all stayed in tact and came out in tact. The difference is the tip will rupture at pinholes instead of stretching into a baloon.

That is a 4500 dollar engine, and that is just parts and machine shop work not counting my labor, so no you will not buy that and a truck for 400 dollars.

When Autozone was selling off Motorcraft/Beru inventory I bought all they had in two stores for 1.99 each.
But if I needed to buy more tomorrow, I would not think twice about paying 50 dollars each.
I know exactly how long it takes to pull a head and reinstall it.
14 hours of hard wrenching for two people plus a return line kit, valley pan, head gasket and rocker cover gasket (200 dollars).

While we are on this topic (and because I am too lazy to go pull one right now), are the beru's (ZD-9) 6v or 12v?

Reason I ask is when I went to manual control I also replaced all of the wiring...each GP sees a solid 12v; I HAD 8 new beru's ZD-9's...3 are now dead - they lasted all of maybe 3 weeks, typically the longest duration on was 6~7 secs, longest was 12.

I read somewhere that the zd-9's were 6v, and if so i am thinking going to a good 12v plug may be more reliable

[tjc transport]

your 86 6.9 should be using ZD-1 glow plugs, not the ZD-9's

[JHoffman93]

Thanks for the feed back guys. Your experianced with the WAP

[Dodge/Cummins]

My '86 uses ZD-9s but I think someone combined old and new GP systems.
Didn't function.
That's why it's manual control now.

[FORDF250HDXLT]

based on my research,i will only be using motorcraft/beru brand glowplugs in my truck too.
there's not really any point to do anything else.
they last forever and a day if your hooked up properly,or know how to operate a manual plug.its doubtful all 8 are bad unless something is seriously wrong-in which case you would then test everything else before burning out 8 more anyway lol.
so for 10 bucks a pop,and what should go 200k-300k miles shoot.....you cant run spark plugs in a car that cheap hahaha.
dont be tight and try to save $ cus its gunna bite ya in the butt when it comes to swollen up plugs iv been reading.
some things you can save $ on.
glow plugs is just not one of these things.

(when you have a couple bad GP's,its not like a wear item,like a spark plug,and it means you should replace all 8.the others can go for another 100k miles! or more.just replace the bad ones guys)
